Limitations

The translator can't do the following:

• Translate English into Toki Pona. Here's why.
• Translate possibly lexicalized compounds such as translating "tomo tawa" into "vehicle".
• Translate Tokiponized proper words into Untokiponized words such as translating "Manka" into "Minecraft".

The following are unrecognized by the translator. ✏️ means it is a limitation due to being work in progress and it will be lifted soon.

• ✏️ Whole sentences, the translator can only translate phrases
• ✏️ "a" particle
• ✏️ "pu" content word
• ✏️ "X ala X" constructions
• Multiple sentences (At most 2 sentences are allowed) Here's why
• Non-pu vocabulary ("tonsi" is recognized)
• Non-widespread Toki Pona additions or "nasin"
• Quotation
• Preverb with modifiers other than "ala"
• Preposition with modifiers other than "ala"
• Clause* with both "li" and "o"
• "kepeken" as headword or modifier
• "taso" as headword (it can be used as modifier)
• "anu" as content word
• Multiple "pi"

There are even more pedantic limitations listed in the source code: src/filter.ts. Some of the limitations might be lifted later.

*Clause refers to the whole sentence or part of sentence found before and after the "la" particle.
